About the Show

America's network of national parks represents vast, dense expanses of virtually unexplored wilderness — hotbeds for mysteries and the unexplained. Each episode delivers several haunting stories to add to the backdrop and natural beauty of some of the country’s most famous national parks.

While some believe the random flashes of light at Glacier National Park in Montana are evidence of extraterrestrials, a trail of clues leads to an even more shocking theory: that the technology causing them may be Nazi in origin.
